She is talking about her 3-year-old daughter Erin, who was in the car with her sisters outside the Windsor store.

“We were playing in the car,” said sister Lauren. The girls had apparently been messing around with quarters.

Suddenly, Julie noticed something wasn't right.

“I realized ... she looked like she’s, she looked like she was struggling,” Julie said. “So, I think she’s choking.”

It turns out the mother of four girls – ages 1 through 7 – was right. Her daughter was choking.

“So, I started hitting her in the back,” Julie said.

That didn’t work. So, Julie started shouting for someone to call 911.

“It was very frightening,” Julie said. “I knew I needed help.”

That’s when help arrived.

“Someone came over and said she was a nurse and just hit her on the back really hard and a coin came out,” Julie said.

That coin was a quarter. And just like that, the nurse left the parking lot.

“Seemed like she had a child with her, so she had to go,” Julie said.

Julie said it all happened so fast that she never even got the woman’s name once it was over. She is hoping the mystery nurse reaches out to her because Julie has something she wants to tell the mystery nurse.
